SPECIFICATION forming part of Letters Patent No.`737,-163, dateduAugust25, 1903.

Original application led February 6. 1902, Serial No. 92,851. Dividedand this application iiled May 29, 1902. Serial No.109,521.` (Novrnodel.)

' To all whom it may con/cern.-

- Be it known that I, CHARLES H. SHEPARD, a citizen of the UnitedStates, and a resident of the borough of Brooklyn, city of New York,

in the county ofKings and State of New York,

v have invented certain new and useful Improvements in Type-WritingMachines, of which'the following is a specification.

^ This case is a division of my application ro filed February 6, 1902,Serial No. 92,851.

My present invention yrelates to caseshifting and line-lock `mechanismsfor type- Writing machines. '5

vIt has been difficult heretoforewhen operating a type-Writing lmachineat high speed to so time the successive operations of the shift-key thatthe upper and lower case printing characters will appear in properalinement. If, for instance, there isv a sluggishzo movement of theshifting mechanism or a premature operation of a type-key, theimpression made before the completion of the shifting operation iseither out of alinement or a blurred and imperfect impression isproduced upon the paper, and in some instances the impressionwillinclude a part of the upper-case and a part of the lower-case character.In correctingV such mistakes? the appearance of the page is marred andmuch 3o time and labor consumed. Still other faulty operations areliable to occur .in some typewriting machines heretofore devised, suchas the clashing or interlocking 0f the type-carriers or other parts.

One of the objects ofmy presentinvention is to overcome the dif'cultiesabove referred to and to provide at the same time simple and efficientline-lock mechanism whereby the type-carrie'rsvmay be automaticallylocked reference characters indicate corresponding out of operation'whenan end 0f a line is parts in lthe various views, Figure 1 is a ver-5o 'tical sectional view, partly'in section, of one form of type-writingmachine embodying my invention, the section being taken from front torear of the machine. Fig.` 2 is a like View ofthe same, showing adifferent `disposition ofthe parts. Fig. 3 is a detail iisolateddiagrammatic perspective view of the case-'shifting mechanism, togetherwith Qthe means employedforpreventing an operiation of the type-carriersWhile the case-shift- 6o ing mechanism is being'operated, as well asfthe line-lock mechanism, which cooperatesA `therewith.

Fig. 5 is a de- 65 ltail isolated side` View 0f aportion ofthe Eblocking and line-lock mechanism. Fig. 6 is a side viewof one of the blocking fingers or catches and the arm which c'arriesit.

In the various views parts have been om-it- 7o tedV or broken away tomoreclearly illustrate other features of the structure. A

I have shown my invention applied to a No. 6 Remington machine, thoughit should be understood that the invention or any one lor more of theseparate features thereof may 'be applied to any other character oftypewriting machine. l

The frame 1 is surmounted by a top plate 2, wlichsupports upright studs4, to which 8o the traverse-rods 5 6, respectively, are connected.lTheusual carriage 7 moves from 'end to end of the machine on thetraverserods and carries a platen-frame 8, in which fa platen 9 isymounted to revolve. The front 85 end of the platen-frame is supportedupon a -shift-rod 10, which is connected to the vupper ends of uprightshift-arms 11 12, located near lthe opposite ends of the machine andsecured to a rock-shaft 13, that isV adapted to 9c rock' in bearingsformed'rinarms or supports- 14D, which depend from the top plate 2. The.shift-rodi() is moved transversely, Vas will hereinafter more clearlyappear, to move the `platen-frame and platen in a direction trans'- 95verse to its feed to change the case-position thereof. This transversemovement ofl the platen and its frame is limited by stoppins 15, carriedin the usual manner by the carriage 7 at each end thereof and whichcooperate with each end of a projecting pivot rod or shaft 16, whichpivotally connects the platen-frame to the carriage 7 through the usuallinks 17.

Character key-levers 18 are fulcrumed at 19 in the frame 1 of themachine and a're provided with linger-keys 20 and restoringsprings 21.Each key-lever 18 is connected to a link 22, which is in turn connectedto a type bar or carrier 23. A spacing key or bar 24 is connected ateach end to a key-lever 25,.

both of which are likewise fulcrumed at 19 upon opposite sides of thekeyboard and are provided with restoringsprings 21. The parts thus fardescribed constitute a portion of the well-known No. 6 Remingtonmachine, and a more elaborate description thereof is deemed unnecessary.

Extending transversely beneath the keylevers 18 and 25 is the usualuniversal bar 30, which has connected thereto at each end a link 31, thelinks being connected at their upper ends 32 to a transversely-extendingbar 33, which is carried by an arm 34 that extends from a rock-shaft 35,mounted in bearings in the arms 36, that are secured at 37 to aplate-like bracket 38, which extends downwardly from the top plate 2.The rockshaft 35 is restored to the normal position by a spring 39,which is secured at one end 40 to the bracket 38 and is secured at itsopposite end 41 to the rock-shaft. Extending rearwardly from therock-shaft 35 is a crank-arm 42, which is pivoted at 43 to a link 44,that in turn is pivoted at 45 to a two-arm lever 46, that is pivoted at47 to a depending bifurcatcd bracket-arm that extends downwardly from abracket-plate 48, that is secured by screws 49 to studs 50, whichproject from the plate-like bracket 38. The rear end of the two-armlever 46 is pivoted at 51 to a link 52, which actuates suitablefeed-dogs 53, that coperate with an escapement-wheel 54, operativelyconnected to a shaft that revolves in av bearing 55, secured to the topplate and carrying at its forward end a feed-pinion 56, that meshes witha feed-rack 57, carried fby the carriage in the usual manner.

Referring particularly to Fig. 3, it will be observed that the shiftingarm 11 at the righthand side of the machine extends downwardly beyondits pivotal center and forms two arms 93 and 94. The arm 94 is pivotedat 95 to a link 96, which has its opposite end pivoted at 97 to ashift-key 98, which is provided with the usual finger-key 99 and ispivoted at 100 (see Fig. 2) to an upwardly-extending inverted- U-shapedbracket 101, that is secured to an arm 102, which projects laterallyfrom the frame 1 of the machine. The shifting arm 12 at the oppositeside of the machine is provided with a depending portion 103, which hasa link 104 pivoted thereto at 105. A screw 106 projects through a slot107 in this link and is threaded into an opening in the part 103. Thepin 106 thus constitutes a stop which limits the movement in oppositedirections of the link with relation to the part 103. The upper end ofthe link 104 is pivoted at 108 to a connecting rod or link 109, that ispivoted at 110 to a U-shaped yoke 111, that surrounds a shift-key lever112, which is pivoted at 113 to a fixed arm 102a of the machine in thesame manner as the shift-key 98 and is provided with a finger-key 114.The depending part 103 likewise has pivoted thereto at 115 a shiftingpiece 116, that is apertured at 117 for the reception of a pin or screw118, that is secured to the piece 103 and projects through said slot oraperture 117 and limits the movement of the shifting piece with relationto the part 103. One arm 119 of this shifting piece is provided with alaterallyprojecting finger or pin 120, which extends into an opening 121in the link 104. Another arm 122 of the shifting piece has connectedthereto at 123 a spring 124, the lower end 125 of which is secured to ascrew-eye 126, that is fastened to a fixed portion of the machine.

From the foregoing description it will be understood that when the partsare in the position represented in Fig. 3 of the drawings the spring 124will exert a pressure to maintain the shift-rod 10 in the foremostposition, where the platen is maintained in a position to coperate withthe lower-case type on the type-bars. When,however,the fingerpiece 127is moved up, such movement is effective to turn the shifting piece 116on its pivot 115, thereby moving the upper end 123 of the spring to theopposite side of the pivot 115, at the same time moving the upper end ofthe link 104 forward to the opposite side of the pivot 105 thereof. Thespring 124 is at this time eective to maintain the shiftrod 110 in therearward position, at which time the platen is in a position to receivethe impact of the upper-case type on the typebars. When the parts are inthe position represented in Fig. 3, the finger-keys 99 and 114 areadapted to momentarily shift the shift-rod 10 and the platen which isoperatively connected thereto to change the printing position thereoffrom lower to upper case. When, however, the finger-piece 127 has beenmoved upwardly, as previously described, a depression of the shift-keyis effective to temporarily shift the platen from the upper-caseprinting position4 to the lower-case printing position. Thecase-shifting mechanism thus far described constitutes a part of thewellknown No. 6 Remington type-writing machine and need not be furtherdescribed.

The depending arm 93, hereinbefore referred to, has arearwardly-extending rod 128, pivoted thereto at 129. This rod isprovided with a laterally-extending pin 130, that projects into aninclined slot 131 in an upwardlyextending arm 132,which is secured to arockshaft 133. This arm has pivoted thereto at 134 a blocking piece orfinger 135, which is normally maintained in a fixed relation to IOO IIO

the arm 132by a spring 136, which is Yconnected at one end 4to thefinger 135 and is se.-

cured at its opposite end'i'e/ totte arm 132.' The ,rock-shaft -133 isprovided near its oppo site endfwith a secondv upwardly-projecting arm138,that corresponds tothe arm 132, and,

like said arm, it has pivoted thereto at 139 a. blocking piece or finger1 40,wh ich is normally,

maintained in a fixed position with relation to the arm by a springsimilar to the spring 136, hereinbefore described. The rear endof therod128 is pivoted at 141 to an upwardlyextending link 142, which ispivotedl at its upper end 143 to one arm of a bell-crank. le ver 144.The other arm of this bell-crank lever lis preferably rounded at its end145 and is seated Within ya slot of a yoke 146,*which yarms 132 and 138,togetherfwith their blockharv33 andwill' be `maintained yin 'the spaceslformed between the projecting arms 153 and tends to maintain the racktoward the right,`-

but permits under conditionswhich will here inafter appear a slightlongitudinal movementof the rack. The rack 147 carries an adjustablestop `or line-lock abutment 151, with which a cooperating ,trip orabutment 1,52, carried by the carriage,v is adapted toy contact in thetravel of the `carriage from right to left oriny the direction of itsfeed. l

In the operation ofthe case-'shifting mechanism and the automatic locktherefor the blocking-lingers 135`and 140 are normally maintained eitherj ust forward or back of the transversehar 33, or what maybe termed thedog-rocker frame. Vihen the parts are in the position to writelower-casecha'racters,

as shown in Fig. '3, a depression of either of the temporary shift-keys99 or" 114 or an up ward movement of the permanent` shift-key 127willcau'se the shift-rod 10 to bevmoved toward the rear of the machine.This movement of theshift-rod and the parts connected theretowill causethe rod'128 to ybe' moved forward, togetherfwith the arrn 132,v con!nected to said rod,',thus .producing a rocking 4movement of the shaft133,v which effects a like movement of the arm 138 at the' other Theforward move# ments ofthe arms 132'and 138 bring the block-.

side of the machine.

ing-fingers into the path'of the transverse bar 33, audit cannot bedepressed until the ing-fingers, have completed their forward movement.At' the completion of the forward movement of these parts theblockinglingers will have j ust cleared the transverse the transversebar to which they are secured.

It will'be, understood that if the operator at-f` tempts to depress acharacterlkey or' the space-bar during this shifting operation, 'theblocking-'fingers will arrest a movement of the transverse bar 33, thuspreventing an actuationV of the type bars or escapement mechanism. Assoon, however, as the shifting movement has taken place theblockingfingers areclear of the transverse bar 33 andA the fingers 153connected ther eto, and the. operator may at this time depress thecharac-` ter-keys or the spacingkey.` When theper- ,manentshiftingdevice is moved by raising the finger-piece 127, so that all uppercasecharacters will be Written, the arms 132 and 138 and theblocking-.fingers carried thereby will bemoved forward tothepositionrepre-I sented in full lines of Fig. 2 of the drawings. A depression ofthe temporary shift-key114 or a movement of the finger-piece 127 to theposition shown in Fig. 3 will at this time cause the blocking-fingers tobe moved with theirv arms toward the rearof the machine and across thepath ofmovement of the`trans; verse bar 33 in order to prevent adepression thereof until the'completion of the caseshifting movement.

Should the operator attempt to actuate the' finger-piece 127 von-eitherof the shiftkeys 99 or 114 when a character-key orthe spacekey is partlyor fully depressed, it will merely 'result' in the blocking-fingersbeinghrought into engagement with either side of the trans- Vverse har33 or the arms 153 thereof, and the pivotedl lingers will yield againstthe tension of their springs, so that no injury can be done either tothe rocker-frame or tliengers. As. soon as the finger of the operatorisremoved -from the keys the blocking-fingers will resume their normal[positions withrelation to the,

arms which carry them, the springs of said blocking-arms restoringthemjto the normal position.

and-slot connection 130 131 and through the rod-shaft 133 to thecorresponding arm 138. If the parts are in the lower-case printingposition, (represented in Fig. 1,) the blocking-fingers 135 and'140,carried by these arms, will be projected beneath the transverse bar 33and thus prevent the depression thereof. If, however, the parts are inthe upper-case printing position, then the arms 132 and 138` willnormally assume the position shown in full lines in Fig. 2 and theactuation of the line-lock mechanism will move the arms forward,together with their blocking-fingers, to the position shown in dottedlines in Fig. 2, where they will cooperate with the ingers 153, carriedby the transverse bar 33, to prevent a depression of the bar and anactuation of any of the character-keys or the spacing-key.

From the foregoing description it will be seen that theinstrumentalities which enter into the mechanism for automaticallypreventing an actuation of any of the character-keys or the space-keyduring the shifting operation from the lower-case printing position tothe upper-case printing position, or vice versa, likewise enter into andconstitute a part of the line-lock mechanism, so that the one set ofmechanism acts in a twofold caacity. p

Should the operator desire to write one or more characters after theline-lock mechanism has been operated in order to insert one or moreadditional characters, it is merely necessary to push in the button 154,that extends forwardly Irom the top plate 2 of the machine and which isconnected to a rearwardly-extending rod 155, that is guided in suitablebearings beneath the top plate and is provided at its rear end with anupwardlyextending finger 155", that is seated in alongitudinally-extending recess or slot in an arm 156, that is securedto and projects downwardly from the rack 147. The eiect of this movementis to rock the rack 147, thus carrying the stop or line-lock abutment151 out of the path of the coperating abutment on the carriage, and thespring 14:9 will restore the rack to the normal position, therebyreleasing the line-lock to permit one or more additional characters tobe written. When the finger-piece or button 154: is released, it,together with the parts connected thereto, are restored to the normalposition by a coiled spring 157, which bears at one end against the rearface of the button and at its opposite end against one of the bearings153.
